Proposed and Installed Offshore Wind Interarray Cable Layouts

United States offshore wind data detailing proposed or installed cable linkages between turbines and offshore substations. The Department of the Interior provides this information for project planning review and permitting, with data updated as new public information is released.

Use Cases

• Model cable route density and length using proposed layout coordinates.
• Assess spatial overlap between cable arrays and marine habitats using geospatial features.
• Compare multiple proposed layout options for a single wind farm project.
• Forecast infrastructure placement changes by tracking updates to proposed cable linkages.

Strengths

• Data includes multiple proposed layout options for some projects.
• Covers both proposed and installed cable linkages.
• Available in multiple geospatial formats including GeoJSON and KML.

Limitations

• The final permitted cable placement and count may differ from the data presented.
• Specific row counts and temporal coverage of projects are not provided.
• Data completeness depends on lessee submissions for planning review.
